The design for a chromatography column which has three powered cylinders for lifting the adapter assembly above the column tube, or lifting the column tube above the base assembly, to provide access to the interior of the column for maintenance purposes. This design obviates the need for heavy overhead lifting devices, such as a hoist or crane, to lift the adapter assembly or column tube. 

The ornamental design for a chromatography column, as shown and described.
